Application November 1 9 Claims.

My invention relates to apparatus for garbage disposal and more particularly to improvements in structure of this character over that shown in my copending application, Serial No. 592,922. The principal object of my present invention is to provide disposal apparatus of simpler construction and of neat appearance that can be readily installed at low cost during or after building of the house or apartment wherein it is to be used.

In accomplishing this and other objects of my invention I have provided improved details of structure, the preferred form of which is illustrated in the, accompanying drawings, wherein:

Fig. 1 is a central vertical section of a garbage disposal installation embodying my invention, the door member and auxiliary tray being shown in closed position.

Fig. 2 is an enlarged view in vertical section '20 of the upper end of the disposal apparatus showing the door opened and its associated auxiliary tray in position for receiving garbage.

Fig. 3 is a horizontal section on the line 33, Fig.2, showing a plan view of the door member and auxiliary tray and particularly illustrating the manner of limiting outward sliding movement of the door from a chute opening.

Fig. 4 is a fragmentary perspective View of the garbage chute with the door member and auxiliary tray in open or garbage-receiving position.

Fig. 5 is a similar view inperspective showing the door member and auxiliary tray in disassembled relation and disassociated from the chute opening.

Fig. 6 is a detail perspective View of a housing for receiving and supporting a garbage container in sealed engagement with the chute.

Referring more in detail to the drawings:

1 and 2 designate inner and outer walls and 3 a floor of what may comprise a kitchen or other room from which garbage and the like is to be discharged and 4 designates a chute terminating at its lower end below the floor 3, as, for example, in a basement and having its upper end extending to a point above the floor and provided with a lateral opening 5 for convenient discharge of garbage into the chute.

The chute is preferably constructed of metal and its extreme upper end is reduced in depth as indicated at 6 for projection above the lateral opening to produce a collection chamber '7 for substantially preventing passage of fumes and gases through the lateral opening, but to promote movement of these gases upwardly through a vent sas City, Mo., vassignor of agan Willey, Kansas City,

pipe 8 secured in a top wall 9 of the extension and leading from the building in any suitable manner. The side of the chute adjacent the interior of the room is preferably covered by a facing member 10 which may be formed of porcelaincovered metal or other material of neat appearance and having an opening 11 registering with the lateral opening 5 of the chute, the facing member preferably including an outset portion 12, projecting slightlyinto the room to cover the corresponding side of the chute and having a peripheral flange 13 whereby the facing member may be secured to the inner wall of the room as shown at 14.

In my preferred form of construction the outset portion of the facing member tapers inwardly towards its upper end and an outwardly directed flange 15 surrounds the side and upper edges of the opening 11 for a purpose presently described.

In' order to seal the lateral opening comprising the registering openings of the chute and facing member, and to facilitate discharge of garbage into the chute a door member 16 is provided of a width to slidably move into the lateral opening and is provided with an inset inner end portion 17 to produce a shoulder 18 for pivoting on the lower edge of the opening and for limiting inward sliding movement of the door into the opening. The side and upper edges of the door are turned inwardly to form a flange 19 for co-operating with and overlying the flange 15 to provide an effective seal for the opening when the door is closed.

As is most clearly illustrated in Fig. 2, a primary tray 20 having a bottom 21 fixed in any suitable manner, as by welding, to the inner face of the door is provided with an inclined lip 22 adapted to extend into the chute, and side walls 23 of the tray are spaced sufficiently from the flanges 19 to pass freely into the lateral opening. Resilient arms 24 having their inner ends fixed by rivets 25 to the side wallsof the tray and opposite ends 26 normally spaced outwardly from the walls to engage the inner side of the facing member serve to prevent outward sliding movement of the door member from the opening, but, as will be apparent, permit unhampered insertion of the door into the opening.

An auxiliary tray 27 having a perforated bottom 28, side walls 29, a closed outer wall 30 and a lip or inner wall 31 of greater inclination than the lip 22, is provided to slide between the walls of the tray 20 and is preferably latched thereto by inwardly and downwardly directed ears 32 engaging the upper edge of the side walls 29 and forming a part of the walls 23 of the primary tray. Attention is particularly directed to the angular relation of the ears 32 to the upper edges of the walls 29, the purpose of the limited spacing produced thereby and of a corresponding amount of spacing reserved between the dischar e lips of the primary and auxiliary tray members being to effect continued rocking movement and a resulting jar of the auxiliary tray after the door member has reached fully closed position as shown in Fig. 1, thereby tending to forcibly discharge particles of garbage adhering to the auxiliary tray. A knob or button 33 may be fixed to the door adjacent its upper edge for facilitating operation of the door and tray members.

The lower end of the chute preferably communicates with a housing 34 supported in fixed position in any suitable manner and having a lateral opening 35 through which a garbage container 36 may be inserted from the exterior of the building. In the present construction, as well as in the apparatus described in my copending application, Serial No. 592,922, I prefer to effect sealing engagement of the container with the chute when a door 3'7 of the housing is closed and in the present instance I accomplish this result by pivotally mounting a false bottom 38 on a floor 39 of the housing by means of side bars 40 fixed to the false bottom and movably connected to rocker-arms 41, pivotally mounted on brackets 42 secured to the bottom of the housing, the bars 40 being guided by brackets 43 fixed to the side walls of the housing. A rod 44 journaled in bearings 45 mounted on the floor of the housing is provided with oifset end portions 46 for bearing engagement with the rocker-arms 41 and an upwardly directed portion 4''! of the rod is bent outwardly and upwardly as at 48 and is operably connected with the door of the housing by means of a link 49 so that closing of the door will force the false bottom upwardly to firmly engage the garbage container with the upper wall of the housing and opening of the door will release the containers from such sealed position for removal from the housing.

The manner of disposing of garbage with apparatus constructed and assembled as described would be as follows:

When desiring to discharge garbage into the chute it is merely necessary to open the door and to place the garbage in the primary tray in case the secondary tray is not used. Upon closing of the door the garbage is automatically discharged into the chute for passage into the container. The auxiliary tray may obviously serve the purpose of a colander usually placed in the kitchen sink, and upon collection of the garbage therein the door to the chute is opened and the auxiliary tray is moved to latching engagemerit therewith so that closing movement of the door will tilt the auxiliary tray for discharge of its contents, and in addition will jar the tray to dislodge particles of garbage adhering thereto.

To remove the door member from the lateral opening it is merely necessary to reach into the opening after the door is opened and to press the resilient fingers against the side wall of the primary tray, whereupon the door assembly can be withdrawn from the chute.

At regular intervals, or as often as required, the door to the cabinet 34 is opened and the garbage container is removed therefrom by the collector in the usual manner. Because of the collection chamber at the upper end of the chute,

odors and gases arising from the container and chute will tend to pass upwardly through the vent instead of escaping through the lateral opening when the chute door is open.

From the foregoing it will be apparent that I have provided apparatus for disposing of garbage in an easy and sanitary manner and that the apparatus described can be readily installed during construction or after completion of the building wherein it is to be used.
